IMPROVEMENT IN BARREL-PAINTING MACHINES.

Specification formingpart of Letters lPatent No. .174,477, dated March 7, 1876; application tiled l December 1e, w75.

To all whom 'it may concern:

' Beit known that I, MARY 1?; CARPENTER, of NewYork, in the county and State ofNew York, have invented a new and useful Machine for Painting Barrels; and I do Yhereby declare thatth'e following is a full, clear, and exact description of the same.

- Mylinvention consists in a novel construction, arrangement, and combination of aframe, and vof mechanism carried thereby, whereby paint is applied to the entire surface of the l sidesand heads of a barrel or cask by means of revolving brushes or rollers supplied lwith paint from fountains connected therewith, and l whereby provision 1s made for the automatic action of the parts to receive the cask to be painted, and to discharge itafter the comple tion of the painting operation. y

In carrying out my invention I provide a frame for carrying the working parts, which frame may be attached to either' an inclined plane, down which the barrels may descend by their own gravity, or toa level plane,

along which they maybe rolled by an attendant. The supporting-frame `carries three rollers forapplying and distributing the paint to the sides of the barrels, and two other rollers for applying itto the ends or heads. The first onelof the three rollers receives vthe paint from afountain and applies it to the surface, and the other twoof the three distribute it thereon; The first one isarranged `in stationary'- bearil'lgs, and always remains in the same position, andthcother two are attachedy to pivotedarms, to allowthem to rise and' fall to receive a barrelto be painted-and permit it to be removed after being painted. l-nThe two end rollers'are alsoattached to'apizvoted arms, to allow them to swing laterallytdreceive and ,releasethebarreh and each yof theserollers is supplied with paint from a separate fountain. The swinging motion .is imparted to the pivoted arms by means of cams'and slides operated by the shaft which carries the, principal roller, or by the main driving-shaft, or both.

The barrel `is rotated bythe-friction of the' rollers,and'the lpaint is thoroughly applied andldistributed over all parts lofI the surface thereof;

The accompanying drawing represents an apparatus constructed according to my invention, Figure 1 being a longitudinal vertical section; Fig. 2, a transverse vertical section, and Eig. 3 a detail view.

The carrying orsupporting frame B may be of any suitable construction, and the plane A,

to which'it is attached, may-be either level or inclined, but is here shown as inclined, so that the cask O may roll down the ways or tracks a by its own gravity. The rollers for applying and distributing the paint may consist of revolving brushes, or they may be covered or faced'with. composition or any suitable substance,y and their profiles correspond with the general .conformation Qfthe surfaces to which-y they are applied. The principal roller D is.v

kattached to and carried by a shaft, E, which isdriven by the main driving-shaft Ex by means of gearing c f. The shafts E and E are arranged in stationary bearings in the frame B, with the shaft E in such a position as to cause the roller Dto revolve in contact with the sides of the cask immediately over and parallel with its longitudinal center when in position to be operated upon, as shown.

The roller D receives the paint from a fountain, which is here represented as consisting o'f a hopper, Gr, attached to the frame B, and provided with a conduit, g, for conducting the paint to the surface of the roller, and with an adjustable gate, g", for regulating the quantity of paint' flowing from the fountain. duit may be constructed and arranged to deliver the paint through a series of perforations, y as shown, or in a stream of continuous width,

or in any other suitable manner. The rollers D1 D2, fordistributing and spreading the paint on the surface after its application thereto by the main roller, are each carried by a frame or pair of arms swinging from the shaft E, so as to allow the rollers to rise and fall. The roller D has its bearings in the lowerv portions of a pair of arms, Hl, which are suspended from the shaft E by said shaft passing through perforal tions in their .npperportions,` inv such a manner as to cause said frame or arms 'to' operate as ai .lever, with the shaft E for the fnlcrum.v

Thefupper end of one`of the armsrHleX- The contends beyond the lfulcrum or shaft E, and is provided with a slot or notch, h', (see Fig. 3,) with which engages a pin or stud', i1, projecting from a plate or bar, l1, arranged to slide vertically in a recess or'guides in the frame B.

The driving-shaft EX carries two disks or wheels, K1 K2, near its ends, but preferably on the inner sides of the frame B. On one side of the wheel K1 is a groove-cam, k1, with which engages a pin or stud, 'j1, projecting from the upper portion ot' the slide 11.

As the shaft F1x revolves, the frame H1 remains stationary as long as the coneentricportion of the cam k1 remains engaged with the pin j1; but as soon as the eccentric portion of the cam reaches said pin 71 the slide I1 is depressed, so that the pin or stud` i1, engaging with the notch h', raises the arms or frame H1 until the lower side of the roller D1 is about on a level with the lower side of the main roller D, and holds it in said position until the concentricportion of the cam againreaches the pin, when the roller D1 is allowed to descend to the position shown in Fig. 1.

The roller D2 hasv its bearings in a frame or pair of arms, H2, one of which is notched, and both of which are suspended from the shaft -E in the same manner as those just described,

'but opposite thereto, so that when a cask is in position to be operated upon by the rollers the main or upper roller is immediately over the longitudinal center of the cask, the roller D1 bears against one side and the roller D2 against the other side, and the three rollers 1) D1 D2 occupy a triangular position with relation to each other, as lshown in Fig. l.

The cam-wheel K2 carries a groove-cam, k2,

similar to that above described, but arranged in a reverse position, so as to operate at a different time. The cam k2 acts upon a slide,

12, provided with pins or studs i232, in the same manner as before described. Y

' The parts being 1n motion, when the eccenpin or stud f2, the slide I2 isdepressed, sov as to raise the frame or arms H2 and roller D2, as before described, and thus allow a eask to pass under the roller D2 to the position shown in Fig. 1. When in this position the paint is received from the fountain G by the roller D, and deposited upon the surface of the cask, upon which it is thoroughly spread and distributed by the two rollers D1 D2. Said two rollers may have their shafts connected with the shaft E by means of belts and pulleys, as shown. As the cask is held between the three rollers D D1 D2, as shown, the friction of said rollers causes the cask to revolve, so as to bring every portion of its sides in contact with them, and thus insure the thorough spreading and distribution of the paint. When the eccentric portion of the cam k1 reaches the pin 7'1 of the opposite slide I1, said slide is depressed, so as to raise the frame ory arms H1 and roller D1, and allow the painted barrel to roll out. As the revolution of the shaft continues, the roller D2 is again raised for the admission of another cask, and the operation proceeds, as before described.

.. The casks to be painted may berolled along one at a time, or a number of them may be placed on the inclined plane, as shown.

For painting the ends of the cask, I employ two rollers,which are preferably conical in form, and are arranged tc bear against the ends of the cask as it revolves. These rollers are alike in their arrangement and operation, and simultaneous in ltheir action, and a description of one 'will apply with equal propriety to the other. In the frame B, transverse to the axis of revolution of the cask and rollers, a rockshaft, L, is arranged in suitable bearings.

g From this rock-shaft an arm, M, extends down- 'ward, and is divided into two branches, m m, :which carry the bearings for a conical roller, 3N, arranged to bear against the end or head A`of the cask C. The arm M carries a hopper l or fountain, P, for supplying paint to the roller. On one'side of the rock-shaft L is a groove, l, running longitudinally of said shaft.

To the frame Bis pivoted one end of a lever, R,

near the other end of which is a lateral pin or stud, t, for engagement with a peripherical icam, T, on the face of the wheel K1 or K2. 'Between this pin or studt and the fulcrum of the lever is another lateral pin or stud, s,

which extends into .the groove l in the rock- I shaft L. The motion of the lever B is limited and guided by means of a stationary pin, r, ,and transverse groove r2. A spring, n, attached to the frame B, and bearing against the lever, has a tendency to keep it pressed upward. When the concen- (Shown in Fig. l.)

tric portion of the peripherical cam T is beari ing against the'pin orstud t, the arm M hangs lin such a position as to cause the conical roll- 7er N to bear against the head of the cask, so as to revolve by friction therewith, and'apply tric portion of the cam k2 engages with the-` the paint thereto. When the eccentric portion of the cam T bears against` said pin t the lever R is depressed, and the pin s, working in the groove l, oscillates the rock-shaft L, causing the arm M to swing outward and remove 4 the conical roller N from contact with the head of the cask. By a suitable arrangement of v,the cams and their connections with relation Ito each other this outward movement of the end rollers will take place at the same time that the roller D2 is raised to admit a cask to be painted,y and at the same time that the roller D1 is raised to allow the eask to roll out to :make room for another, by which means the `end rollers will present no obstacle to the admission of a cask' to be painted, or its expul- 'sion after being painted, but will only bear against the surfaces of the heads or ends while the c ask is going through the painting process.

What I claim asnew, and desire to secure by Letters Patent, is-

f plying, spreading, and4 distributing paint upon the sides of the Cask, said movable rollers being arranged to rise and fall toprovide for the admission and expulsion of the cask before and after the paintingoperation, substantially as herein described.

2. The combination, with the admitting-roller D2, of the pivoted arms or frame H2, the slide I2, having pins 2 and jz, and the groovecam 7a2, substantially as and for the purpose herein described.

3. The combination, With the dischargingroller D1, of the pivoted arms or frame H1, the slide I1, having pins l and jl, and the groove-cam k1, substantially as and for the purpose herein described.

4. The combination, with the frame B, of the rollers N, provided with paint-fountains P, for applying paint to the heads lor ends of the cask, substantially as herein described.

5. The combination, with the roller N, of the roller-carrying arm M m m, rock-shaft L, lever R, having pin t, and peripherical cam T, for moving said roller toward or away fromthe head or end of the cask, substantially as herein described.
